Abstract
The title complex has been prepared from a reaction of [Ru2O(O2CMe)2(MeCN)4(PPh3)2](ClO4)2 with N,N-dimethyl-1,2-diaminoethane (dmen) in MeOH. The crystal structure of [Ru2O(O2CMe)2(dmen)2(PPh3)2](ClO4)2· MeOH shows the presence of a [Ru2(μ-O)(μ-O2CMe)2]2+ core. The terminal ligands on each metal are a PPh3 and a bidentate chelating dmen. The Ru---Ru distance and Ru---O---Ru angle in the core are 3.271(2) Å and 120.9(4)°. The more electron-donating site of the dmen ligand is bonded at the terminal sites trans to the µ-oxo ligand. The complex displays a visible absorption band at 566 nm (ε, 6960 M-1 cm-1) in MeCN and undergoes a nearly reversible one-electron oxidation at 1.02 V and an irreversible reduction at -0.52 V (vs SCE) in MeCN- 0.1 M [NBun4](ClO4).
